On-line characterization of nanoparticles by single particle ICP-MS utilizing microfluidic devices

In this study, polydimethylsiloxane (PDMS) - glass microfluidic chips (MCs) were designed and fabricated using moulds prepared by a professional 3D printer. The prepared chips were used for the dilution, counting and characterization of nanoparticles (NPs) performing single particle inductively coupled plasma mass spectrometry (spICP-MS) measurements.
